Question

When I try to send unformation about my Age it asking my Gen and then my height. And if I'm writing my height it's asking my gen 2 times and 1 time my age.
How make it works like this:
It asking something i answer something, if answere do doesn't fit, it asking this question again, if answer fits it send new questions wich work with same algorithm.?

Code:
let weight, height, age, dailyNorm, A, proteine, fat, glucide, gen;
let low=1.2, small=1.4, middle=1.6, big=1.7;

const TelegramBot = require('node-telegram-bot-api');
const token = '734206894:... ';
const bot = new TelegramBot(token, {polling: true,
onlyFirstMatch:true, });

bot.onText(//start/, (msg) => {
bot.sendMessage(msg.chat.id,"Бот активирован🤖" , { "reply_markup": {
"keyboard":[["Calculate🍎" ], ["Report🐞"]]
}});
console.log (msg.text);
});

function dataGen(a){
bot.sendMessage(a.chat.id,"Your gen(👦-m,👧-f)?"); console.log (1)
bot.on("message", (msg) => {
if (msg.text=="m"){ gen="m"; dataAge(msg);}
else if (msg.text=="f"){ gen="f"; dataAge(msg);}
else { dataGen(msg);}
console.log (2)
});
}

function dataAge(b){
bot.sendMessage(b.chat.id,"Your age👶?");
bot.on("message" , (msg) => {
if (msg.text>1 && msg.text<100){age=msg.text; dataHeight(msg);}
else{ dataAge(msg)}
});
}

function dataHeight(c){
bot.sendMessage(c.chat.id,"You height📏?");
bot.on("message" , (msg) => {
if (msg.text>100 && msg.text<300){ height=msg.text; }
else{ dataHeight(msg);}
});
}

bot.onText(/Calculate🍎/, (msg) => {
dataGen(msg);
})

I think I have the same issue:

It haves something to do with the chatId. Would be nice to see it fixed.

For the original issue, @inikolaesku, the problem is that .on() does not get removed but is a static listener and it is not linked to one specific message. So you should set only one or multiple (with completely different purposes) .on("message").

For you, @RFlintstone, you are registering a new .onText() every time a user sends a message. Please note that a message listener captures any kind of message.
If you want to capture a specific message, you should set a global .onText(/yourregex/, () => {...}) for each message.

.onText(/yourregex/, () => {...})

I know that but each time the 'chatId' is activated it will execute the reaction one more in the next mention

Ex:

1)
User: /echo Hi 
Bot: Hi

2)
User: /echo Hi 
Bot: Hi
Bot: Hi

3) 
User: just some text

4)
User: /echo Hi 
Bot: Hi
Bot: Hi
Bot: Hi
Bot: Hi
